A low over northern Missouri will intensify as it moves toward Lake Superior. Precipitation ahead of the low will progress west over southern Manitoba on Wednesday.

Looks like mostly a snow event. There is some question as to what type of precipitation will fall during the beginning of the event. Temperatures will be high enough for some rain or a rain/snow mix. However precipitation will make a rather quick transition to snow. But the snow should be wet so that should limit and significant accumulation.
